1. It could be problematic because there are so many different types of Latin American music that it may not make sense to speak of it as a whole. I agree with that statement because there is such a wide variety of Latin American music.

2. Latin American music comes from the people of Latin America, whereas Latin music comes from the people who are descendants of Latin Americans but live in the United States.

3. Ostinatos are a repeated element of music (usually rhythms, but can also be melodies, notes  etc.) They are used it Latin American and Latin music to set the style and keep time.

4. The Habanera pattern can be found in a lot of contradance music. A commob example of the Habanera pattern is in Carmen.
